Notes | Saxifraga aizoides differs much morphologically from S. oppositifolia. The Löves proposed to accept the sections Porphyrion and Xanthizoon as two genera: Anthiphylla and Leptasea. The molecular results (Soltis et al. 1996) indicate that sect. Xanthizoon should be fully merged with sect. Porphyrion. |
